Diesel Masters 12391 Sampson Avenue, Riverside, CA 92503

"Hands down the best diesel shop in the IE. Juan found the problem on my 06 f250 in less than 30 min. I had already gone to several other supposed "diesel pros" who wanted to charge me thousands for a very simple repair. I appreciate what Juan did for me and has earned a new customer to his shop. Glad i decided to give them a try and save myself thousands of dollars in unnecessary repairs. Appreciate the help and would highly recommend Diesel Master for your next repair or service!!"

"I went to two dealers and one diesel repair shop to help find the cause of a rough running engine. After hundreds of dollars spent, I still had the same problem. I was ready to sell the truck at a loss, and move on. After reading positive reviews for Diesel Masster, I was willing to try once more. Juan found an intermittent short in a sensor, repaired it, and my truck now purrs like a kitten. I only trust Juan with my truck, even for oil changes. He is the real deal."

"These are the only mechanisms I trust to work on my Ford Diesels! They know there stuff and they will never charge you for something you didn’t need. I have had them BullrtProof and chip my 6.0 Excursion. It rips and is now reliable. Without them I don’t know how I would be able to keep these 15 - 20 year old trucks on the road! They do all the service on my 6.7 F-250 too."

"Amazing customer service! I took my diesel truck in and right away I was helped. Recommend this shop 100% for all your diesel truck needs!"

"Diesal Masters worked on my F350 about a year and a half ago. I did a full bulletproofing kit with them, and I couldn’t be happier best money I’ve ever spent on my truck. These guys know what they’re doing. I’m extremely impressed. I have no leaks after a year and a half. Everything has worked better than before! Five stars all the way I would definitely use these guys if you have a ford diesel!"
